Creating a monster: The obese mouse, right, weighs 52g while the normal mouse, left, weighs just 20g. The pair are being used by scientists in attempts to create an anti-obesity pill

Being placed into a machine for another experiment, these mice are playing a big part in the continuing fight against obesity.A team from the the Integrated Research and Treatment Centre for Adipositas at Leipzig University are using the animals to test a number of developments they hope will lead to an obesity pill.The team, of whom Eva Boege, pictured below, is a member are analysing tissue samples of both obese people and animals.

They are 800 samples currently stored there, with an expansion in the pipeline.Scientists at the university are looking at ways that hunger and satisfy appetite can lead to university.They are focusing on parts of the brain that are involved in the regulation of hunger in the hope of developing a treatment.Their project also hopes to replicate a number of hormones which could lead to the development of a treatment strategy for humans.

Scientists have long hope to create the elusive 'obesity pill.'A previous study, published last year found that overeating mice don't gain weight when a specific protein is removed from the food.The protein known as klotho, which regulates the body's sensitivity of insulin, could turn obese ice into slim mice when regulated.

Breakthrough: The studies being undertaken at Leipzig University could lead to a treatment to combat obesity
